Add a read-only web dashboard at GET / that displays: - Summary counts for all monitored resources - Domain nameserver state with per-NS records and status - Hostname DNS records per authoritative nameserver - TCP port open/closed state with associated hostnames - TLS certificate details (CN, issuer, expiry, status) - Last 100 alerts in reverse chronological order Every data point shows relative age (e.g. '5m ago') for freshness. Page auto-refreshes every 30 seconds via meta refresh. Uses Tailwind CSS via CDN for a dark, technical aesthetic with saturated teals and blues on dark slate. Single page, no navigation. Implementation: - internal/notify/history.go: thread-safe ring buffer (last 100 alerts) - internal/notify/notify.go: record alerts in history before dispatch, refactor SendNotification into smaller dispatch helpers (funlen) - internal/handlers/dashboard.go: template rendering with embedded HTML, helper functions for relative time, record formatting, expiry days - internal/handlers/templates/dashboard.html: Tailwind-styled dashboard - internal/handlers/handlers.go: add State and Notify dependencies - internal/server/routes.go: register GET / dashboard route - README.md: document dashboard and new / endpoint No secrets (webhook URLs, API tokens, notification endpoints) are exposed in the dashboard. closes #82
